Hmm, USB_INITIAL_DATATOKEN is not used anywhere in the driver.

Btw, when sending data from my program, is it better to send it only when receiving USBRQ_HID_GET_REPORT or via usbSetInterrupt?

Hi, i wrote this code ( http://tm.privatepaste.com/801BrgfCB1 ) based on HIDKeys, but right after connecting it to USB, it only sends "ello\n" when pressing my button on PC0. When i press it again it sends "Hello\n" as intended. Do you have an idea what could be the reason for it...

Will the AVR work correctly with 3.3V? According to the datasheet, it needs 2.7-5.5V for 0-10MHz and 4.5-5.5 for 0-20 MHz.

Edit: Seems to work fine with 3.5V on the AVR.

I'll try that later.. Which voltage should the chip have?

Very odd thing: after moving to PD2 (=INT0) and PD3 it works fine when connecting it to my linux pc.. when connecting it to my windows PC I still get the same errors.

Hi, I tried the PowerSwitch example on my Mega644 but the PC always says that the connected USB device could not be detected and doesn't work properly (libusb-win32 is installed and HIDKeys has the same problem). My layout looks like this: D+ -> 68Ohm -> PC2. PC2 <-> INT0 D- -> 68Ohm -> PC0 + -> 1.5...
